A missing Australian snorkeler looks to have been the victim of a brutal shark attack, the Guardian reports. Bystanders saw a dorsal fin and a struggle before the water turned red and the man disappeared off western Australia; his tattered wetsuit surfaced later. An aerial search later spotted a great white swimming in the area. Brian Guest, 51, was a longtime advocate of shark conservation.

A few hours later in Sydney, a great white knocked a kayaker out of his boat, but he managed to get back in. The Guest attack was Australia’s second shark attack this year; the country sees about 15 annually. “I have always had an understanding with my wife that if a shark or ocean accident caused my death then so be it, at least it was doing what I wanted,” Guest wrote in 2004.
